All you need are 3 INGREDIENTS!
1 cup hair conditioner
2 cups corn starch
1 small bottle Glow in the Dark paint (non-toxic)
Mix the conditioner and corn starch together in a bowl. If dough seems too sticky, add more cornstarch.
Next, dump in your bottle of glow in the dark paint and mix until it's fully incorporated. Once the dough forms a nice ball, you will want to charge it near a lightbulb or flashlight.
If the glow starts to fade, hold it up to a light for a few minutes to charge and keep playing.
